Selling HDD - wiping

I am selling my HDD and I want to erase it.

You need to wipe only one HDD? If so, bothering about DOS environment to launch one of the older apps can be a time-wasting idea.

Get HDDScan (it's free)

And perform write test (called "Erase" in the software). Besides having each LBA overwritten, you'll get a detailed drive health report at the same time.

zero out your glist and plist then wipe it with dban.
